IBM Mirrors Shark Over FC: Page 2 of 3

Adds Tuckwell: "We think we've got a performance advantage that equates to fewer channels, and with fewer channels comes a cost savings."

Analyst Mike Fisch of The Clipper Group Inc. says he's not sure about the performance advantage, but he agrees that the enhancements have improved the Shark product line.

"I dont think IBM is pulling ahead, but this is certainly better than Escon," he says. "You have a three-way horse race among high-end storage vendors with EMC’s Symmetrix, Hitatchi’s Lightning, and IBM’s Shark. They’re all constantly jostling, and it’s IBM’s turn to jostle in that group."

According to IBM, the Shark’s new long-distance data mirroring capabilities will improve disaster recovery and reduce costs. To show the Shark’s extended reach, the company today demonstrated a data mirroring implementation spanning 1,200 miles from to Minneapolis to Lumberton, N.J. [Ed. note: Yes, Lumberton, N.J., world-renowned hotbed of data replication!] The demonstration was made in conjunction with CNT (Nasdaq: CMNT) (see CNT Extends IBM Data 1,200 Miles).

The Shark’s improved disaster recovery manageability will also allow changes to be tracked to data on backup volumes while the primary storage is unavailable. These failsafe measures help to greatly reduce the time needed to resynchronize PPRC volumes after switching from the primary to the remote site, IBM says.
